Due to the Yukawa coupling \(\lambda \)  in Eq.(REF ),
the Higgs boson mass can be naturally uplifted to observed value
for moderate value \(\lambda \ge 0.5\)  at the electroweak (EW) scale.
This specific extension is referred as
the next-to-minimal supersymmetric model (NMSSM) [1]} for \(\lambda \le 0.7\) ,
or \(\lambda \) -supersymmetry (\(\lambda \) -SUSY) [2]} for \(0.7\le \lambda \le 2\) .
Either the NMSSM or \(\lambda \) -SUSY is very attractive from the viewpoint of naturalness argument [3]}, [4]},
as the stringent tension on stop masses required by the Higgs mass in the MSSM is dramatically reduced.
